To all whom it may concern Be it known that l, GEORGE E. SWAN, a citizen of the United States, and a resident of Providence, in the county of Providence and State of Rhode llsland, have invented new and useful Improvements in Braiding- Machine Attachments, of which the following is a full, clear, and exact description.

his invention relates to braiding machine attachments.

The general object of this invention is the provision of means associated with the rubber strands of an elastic braiding machine for causing the operation of the means provided for connecting the braiding machine to the prime mover to release the former from the latter upon the breaking of the rubber strands.

This and other objects of the invention will be more clearly understood from the following detailed description and accompanying drawings.

Figure 1 is a front elevation of thebraiding machine with the braiding machlne attachment mounted in position;

Figure 2 is an end elevation of the braiding machine with the braiding machine attachment in position;

Figure 3 is a side elevation of the clutch interposed between the prime mover and the braiding machine Figure 4 is a top plan view of the upper portion of the braiding machine attachment;

Figure 5 is a side elevation of the braid-' ing machine attachment with part of the lower portion of the stop motion cut away to show the triggers and weight arms;

Figure 6 is a top plan view of the U- shaped lever associated with the weight arms; and

Figure 7 is a vertical section through the upper portion of the stop motion attachment.

Referring to the above-mentioned drawings, a braiding machine, comprising a frame 10 on-which is mounted a sinuous track 11, bobbin carriers 12 and bobbins 13, is shown. A drum 1% onwhich rubber strands 18 are wound is supported on the lower section of the frame 10. The rubber strands 18 pass upward through tubes 15 and over pulleys 16 supported by the upper section of the frame. Bobbins 13 carry the threads 17 which are woven about the rubber strands 18. A. clutch is interposed betwew the braig .machine and the A collar 24 is slidably mounted on the shaft 19 and provided with fingers 25 whiohproject through openings in the collar 23 and engaging in openings in the bevel gear 22 thus connecting it to the shaft. A. lever 26 is provided for raising the collar 2 and has a latch 27 attached thereto for engaging with a link 28 to hold it in raised position. The bevel gear 22 meshes with a bevel gear 29 which is driven by the prime mover. The above-described machine is not part of the invention but is described so that the operation of the stop motion attachment may be more clearly set forth.

Acasing 30 (see Figure 7) is pivotally mounted on the frame 10 by means of a threaded bolt 31 fixed to the casing, and a bushing 32 is clamped to the casing by does not project over the sinuous track 11 into the path of the carriers 12 but is of sufiicient length so that it may be operated to extend into the path of the carrier which when it comes in contact with the bolt will swing it and the casing in a horizontal plane. A connecting link 41 is provided to connect the bolt lug with the link 28 with which the slide 27 engages.

Mounted on the lower portion of the frame 10 (see Figure 5) is a plate 42 which carries two posts 43 and 44. Supported by these posts are three axles 45, 46 and 4:7. The axle 4:6 is not in alinement with the axles 415 and t7. A plurality of weight arms 48 are loosely mounted on the axle 46. The number of weight arms will depend on the number of rubber strands carried by the particular braidin machine. These weight arms are not eve y balanced about the axle to but the portion of each arm on one side of the axle is considerably longer and heavier than the portion extending on the other: A number of triggers 49 are loosely mounted on the axle 45, one for each weight arm. The upper end of each trigger is provided with a hook 50 which engages with a rubber strand. The lower end is provided with a projection 51 which engages with the short end of the weight arm and serves to hold the weight arm in a nearly vertical position, as shown in Figure 2. A U-shaped lever 52 is loosely mounted on the axle 47 and is normally held in the raised position shown in Figure 2 by means of a spring 53. The spring 53 is attached to an arm 54 carried by the post 43 by means of a bolt 55 and nut 56. This bolt and nut 55 and 56 are provided so that the normal position of the lever 52 may beadjusted. A connecting rod 57 is interposed between the lever 52 and the bell crank 37 The operation of the device is as follows:

The triggers 49 are engaged with the rubber strands 18, and the weight arms 48 are raised to the nearly vertical position shown in Figure 2 and engaged by the triggers 49. The triggers serve to hold the weight arms in this position as long as they are engaged with the rubber strands 18. The lever 52 is raised to the normal position shown in Figure 2 by the spring 53 thus raising the connecting rod 57 and bell crank 37. The raising of the upper end of the bell crank 37 draws the bolt 34 outward and it does not project into the path of the carriers 12. The lever 26 is then raised, operating the clutch to connect the braiding machine to the prime mover, and the connecting member 28 is moved into engagement with the latch 27 thus swinging the bolt 34 and casing 30 in a horizontal plane into the position shown in Figure 4. The braiding machine is now operating and will continue to operate until the clutch is released, disconnecting the braiding machine from the prime mover. This release of the clutch is accomplished when one of the'rubber strands 18 breaks. Upon the breaking of a rubber strand one of the triggers 49 is released and allows aweight arm to fall into contact with the lever 52. This forces the lever 52 downward and draws the connecting rod 57 and the upper arm of the bell crank 37 downward. The bolt 34 is forced inward by the operation of the bell crank 37 and takes the position shown by the dotted lines in Figure 4. The bolt 34 in this position projects over the sinuous track 11 into the path of the carriers 12 which engage with it and swing it in a horizontal plane. The connecting member 28 is. also swung in a horizontal plane by the swinging of the bolt 34, and the, latch 27 is released, droppin the lever 26 which causes the collar 24 to s ide downward on the shaft 19. This operation releases the bevel gear'22 which now turns loosely on the shaft 19. The machine may be set in operation. again by the connecting of the rubber strand and engagi the released trigger 49 therewith and raising the weight 48' to its nearly vertical position shown in Figure'2.

I would state in conclusion that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the exact details herein illustrated since manifestly the same can be .considerably varied without departing from the spirit of the invention as defined in the appended claims.
